CONDENSERy FOR LO'COMOTIVES.

implication` filed November, 1925Seria1No. 71,468, and `in Sweden November 26, 1924.

Condensers for locomotives are usuallyof the type comprising an air cooled part consisting of condenser pipes or corresponding elements or similar members disposed onV pressure side, said diaphragm `consistingpreferably of a sheet metal plate-,secured to the steam distributing pipes.

Such condensers have '-usuallybeen provided With means to distribute4 the steam tol the diflerentcooling elements, said means consisting, for instance, of steamdistributing pipes in which the cooling elementshave been inserted either directly or by means of collectin.,- chambers common to ajplurality of such cooling elements.

@is is Welly known, the extension of the locomotive in Vall direct-ions is limited by the so called loading gauge, and forthis reason it has been diflicult to place thesesteamdistributing pipes in the most suitable manner whilst maintaining at the same-timethe size of the fans@ y y The present invention refers to condensers of this type, and has for its object to provide means whereby the steam may be distributed to the elements in a more suitable manner than has hitherto beenV possible, Without decreasing the dimensions of the fans. Accord;`

ing to the invention, the steam distributing Vmeans consist of one or more chambers or boxes disposed at the same level as the fans and having a shape conforming to the necessary clearance with respect to the periphery of the fans. Each steam distributing chamchambers preferably made of cast iron.

in embodiment of the invention is shownv by of example in the accompanying drawing, in which Fig. i is a plan View of a condenser according to thepresent invention, whereas Fig. 2 is a section on the line III-II in Fig. l. f

The condenser Vshown comprises an air cooled Vpart consisting of tivo groupsof cooling elementsl and 2 placedon oppositesides of a vertical plane of symmetry throughs-the condenser, and a liquid receptacleB. v In the embodiment shown the cooling elements are placed` along the sides of the condenser, and communicate With the lower part of said receptacle by means of collecting chambers. Arranged above the'receptac'le are fans 8, 9,1() driving the. air necessary for cooling through the air cooled part between vthe elements. The, passage of the air is indicated in 2 bythe. arrows 11 and l2. y

Accordingto the invention, the means fory distributing the steam tothe several elementseonsistofone or more `chambers l and 5 arranged atthe same levelas the fans 8, 9 and' 10.*. The'chambersvhave a Ashape conforming to the periphery of .the -fansvwhilst ,providing for'` necessary clearance.v VConsequently, the chambers will perform the function of the diaphragms previouslyused'and also that ofthe steam, distributing pipes. The ychanfibers have,`. preferably, the same height as the Wings'of the fans. .In the ,em- Vbodiment shown, each steam distributing chamber consists VVof a' plurality of chambers 2A-b, ta, la and 5a, 5l?, 5, 5c1 respectively. These chambers are .preferably made .of cast iron andprovidedwith ribs bywhich they are connected 'with each other by meansof bolts. `The chambers may communicate With each other, butpreferably they are, entirely separate, in ivhich case it is not necessary to provide any packing means between the ldif- Y ferent chambers.

As shown in Fig. .1, the integrating chambers have such a shape that theircross secv tion decreases according to the cooling passage of the Vsteam into the elements. Of

course', by this means amore uniform distribution of thesteam to the elements will be effected. Y v

' By means of an arrangement accordingto the present invention several important advantages are gained. The chambers are preferably cast from the samel material as the` condenser, and, consequently, ther Ysame conditions of expansion prevail in said chambers as in the remaining part of the condenser. By this means the clearance between the fans and the chambers may be made smaller than has hitherto been possible between the fans and the diaphragme, which diaphragms do not follow the variations in temperature in the condenser, but instead have a temperature different from that of the other parts of the condenser. According to the invention it will also be possible to insert the collecting chambers of the cooling elements into the distributing chambers in a more suitable manner, as said distributing chambers, made of cast iron, may be more easily prepared for the inser tion of the collecting chambers, whereby the manufacture of the condenser will be facilitated.

What We claim is 1. In a condenser for locomotives, condenser elements arranged on opposite sides of a vertical plane of symmetry through the condenser7 fans for passing air in heat eX- change relation to said condenser elements7 and means for distributing steam to the condenser elements comprising chambers in the same plane as the fans and shaped to conform to the periphery of the fans.

2. In a condenser for locomotives, condenser elements arranged on oppositesidesof a vertical plane of symmetry through the condenser, fans for passing air in heat eX- change relation to said condenser elements, and means for distributing steam to the condenser elements comprising a plurality of contiguous chambers in thersame plane as the fans and shaped to conform to the periphery of the fans.

3. In a condenser for locomotives, condenser elements arranged on opposite sides of a vertical plane of symmetry through the condenser, fansvfor passing air in heat exchange relation to said condenser elements, and means for distributing steam to the condenser elements comprisinga plurality of contiguous chambers7 in the same plane as the fans and shaped to conform with the periphery of the fans, a liquid receptacle, and steam pipes leading from said liquid receptacle to said chambers, said liquid receptacle being disposed below said Vchainbers and communicating With said condenser elements for drainage of. condensate from said condenser elements.

4L. ln a condenser for locomotives, condenser elements arranged on opposite sides of a vertical plane of symmetry through the condenser, fans for passing air in heat eX- change relation to said condenser elements, and means for distributing steam to the condenser elements comprising chambers Vin the same plane as the fans and of substantially the height of the fan blades, and shaped to conform to the periphery of the fans.

5. In a condenser for locomotives, condenser elements arranged on opposite sides of a vertical plane of symmetry through the condenser, steam distributing chambers communicating with said-condenser elements and adapted to form a roof for said con- Y denser, said chambers having openings therein7 and fans positioned Within said openings for passing air in heat exchange relation to said condenser elements.

Y 6. ,In a. condenser for locomotives, condenser elements, fans for passing air'in heat exchange relation to said condenserelements,

and means for distributing steam to the condenser elements comprising chambers in the saine plane as the .fans and shaped to conform to the periphery of the fans, said chambers and said condenser elements having substantially the same coefficient of er:- pansion.

In testimony whereof We affix our signatures.
